Marketplaces and platforms
A marketplace has at least three kinds of users and each vendor behaves like a small B2B customer. LumoAuth models all of them in one organization structure with per-vendor branding, roles that differ by side, and webhooks for the events your business logic needs.

Vendors want their own sign-in; buyers want none at all
Vendor staff need roles and invitations. Buyers need one tap. Operators need to see both without becoming a bottleneck.
How LumoAuth solves it
Sides as organizations
Each vendor is an organization with its own admins; buyers live in the consumer organization. Docs
Vendor onboarding
Invitations, progressive profiling for business details, webhooks to trigger KYC. Docs
Per-vendor branding and domains
A vendor's staff sign in on a page that carries their brand. Docs
Marketplace-wide and per-vendor roles
Operator roles across the platform; vendor roles inside each vendor. Docs
Fraud at sign-up and at transaction time
Risk scoring, device fingerprinting and step-up for high-value actions. Docs
Events
Webhooks for users, organizations, consents and sign-ins. Docs
